Only way for this to happen on an H2 (AWD) is for something to break rearward of the lockup hub. Take a look at the splines between the intermediate shaft and centerdifferential or even the teeth on the forward sun gear and/or stepped pinion on the center diff.
As long as you have the t-case torn down for repair be sure to upgrade to the new aluminum mode fork (production upgrade to old plastic forks thru end of 2007 or so). You should also upgrade the rear half of the housing to the 2008 version which has a pressed-in rear prop bushing (better bushing and is also replaceable.

It does not seem that sufficient diagnosis was done. No, you cant give a specific diagnosis like that without tearing unit down. It's likely that they told you the most common failure and left it at that. Likely there is a problem with your unit...I think this becomes more of a trust issue than a mechanical one. A second opinion from an independent reputable shop may help but either way, you need to have it fixed. In not using it much, it makes me wonder how it got worn.

hey there i cant tell you what you are missing but i can tell you how to disengage the front wheels . ok you have a vacum line that runs right under the battery and a line that comes up from the front diff. to the same place ( you may have to remove batt and batt tray to get full access to this) un bolt it and temporaly put batt and batt tray back in start it up and decompress this and see if it comes out .... you should here clunking noise if it goes back in ... if thats the case just pull that big vaccum line off .... to test get all four tires off the ground and have some one put it in drive but dont hit the gas it should turn on its own ...if that dont work check the cable that runs down to the differental
